Custom Economy Type

Custom economy type has been added in 1.5.0 version. You can now set economy-type to Cusstom;;<placeholder>;;<giveCommand>;;<takeCommand> to use this feature.

For example, PlayerPoints custom economy type can be set to:

Custom;;%playerpoints_points%;;points give %player% %amount%;;points take %player% %amount%

However, EconomyExchange has directly supported PlayerPoints, so you don't need write this complex string, you just need to write PlayerPoints.
